The newer 1G and 540M microdrives have better specs on this than the
older 360M microdrives.  The older microdrives require about 30% more
power to spin up.  The large number of machines that couldn't supply
this was why IBM went with a smaller spinup current.  I don't have a
1G drive, but I'm told it spins up a little more slowly than the 360M
drive.
